An Azure subscription is required when a virtual network is selected while deploying Windows 365 Enterprise. The following table describes the levels. The correct tuning settings for your network adapters depend on the following variables: The following sections describe some of your performance tuning options. Apps in the Microsoft Store can be pushed to the device, triggered via Intune (MDM). The following options only apply to the applications that use SQL Server Native Client to connect to SQL Server. If the network adapter does not perform interrupt moderation, but it does expose buffer coalescing, you can improve performance by increasing the number of coalesced buffers to allow more buffers per send or receive. If this action doesn't work, it means that the port number isn't being returned to the client. In the Log File Viewer, select Filter on the toolbar. For example, for a default instance, and just use a computer name such as CCNT27. In addition, you can configure RADIUS clients by specifying an IP address range. When you create an environment, you can provide a custom VNET, otherwise a VNET is automatically generated for you. The same set of credentials is used for network access control (authenticating and authorizing access to a network) and to log on to an AD DS domain. For example, consider a network adapter that has limited hardware resources. Azure Virtual WAN brings together many Azure cloud connectivity services such as site-to-site VPN, ExpressRoute, and point-to-site user VPN into a single operational interface. Once you've collected the trace, you can export the trace by choosing File > Save > All Sessions from the menu bar. You can use VNets to: For more information, see What is Azure Virtual Network?. Outbound (egress) traffic incurs charges against the Azure subscription for the virtual network. If ping to the IP address succeeds, but ping to the computer name returns Destination host unreachable or Request timed out, you might have old (stale) name resolution information cached on the client computer. If a network adapter does not expose manual resource configuration, either it dynamically configures the resources, or the resources are set to a fixed value that cannot be changed. Upgrade to Microsoft Edge to take advantage of the latest features, security updates, and technical support. For more information, review Configure a Windows Firewall for Database Engine Access.
